Hanscom Field is a bit smaller than DCA. A Cirrus is a bit smaller than a 737 (or whatever the planes landing at DCA were.) DCA is, oddly enough, immediately adjacent to Washington D.C. and Hanscom is hundreds of miles from D.C. If the sleeping controllers were at Hanscom rather than DCA, this situation wouldn't have blown up nearly as far.
